Abstract:
Die Erfindung schlägt eine integrierte Schaltung zur Umwandlung eines Single-Rail-Signals in ein Dual-Rail-Signal vor, bei dem ein Konvertierungsmittel (500) zwischen einem Dateneingang (501) und einem Datenausgang (502, 503) verschaltet ist. Das Konvertierungsmittel (500) umfaßt eine Speicherzelle, deren Eingang (SZE) mit dem Dateneingang (501) der integrierten Schaltung verbunden ist und an dessen Ausgangsanschlüssen (SZA1, SZA2) im transparenten Zustand der Speicherzelle das logisch gültige Dual-Rail-Signal anliegt. Zwischen den Ausgangsanschlüssen (SZA1, SZA2) der Speicherzelle (SZ) und den Ausgangsanschlüssen (502, 503) der integrierten Schaltung ist eine Schaltungsanordnung (520) angeordnet, die das Vorladen der mit den Ausgangsanschlüssen verbundenen Ausgangsleitungen übernimmt und einen direkten Übergang von der Vorladephase in den logischen Zustand auf den Ausgangsleitungen und umgekehrt sicherstellt.
Abstract:
In one embodiment, a voltage level shifter (810) includes a first p-type metal-oxide-semiconductor transistor (835) having a gate configured to receive an input signal (D) in a first power domain, and a second PMOS transistor (840), wherein the first and second PMOS transistors are coupled in series between a supply voltage (vddout) of a second power domain and a node (820). The voltage level shifter also includes an inverter (850) having an input coupled to the node and an output (Z) coupled to a gate of the second PMOS transistor, and a first n-type metal-oxide-semiconductor transistor (830) having a gate configured to receive the input signal in the first power domain, wherein the first NMOS transistor is coupled between the node and a ground.
Abstract:
In a latch circuit having a bistable pair of cross connected transistors of a first polarity and a third transistor of a second polarity, a current signal greater than a bias current is received at a latch circuit port, amplified with the third transistor, and applied to the latch circuit port. This decreases the time in which the latch circuit port receiving the current signal greater than the bias current reaches a steady state voltage.
Abstract:
A comparator (100) compares input signals in a regenerative circuit (30). Switches (52, 54) isolate the signal inputs (10, 20) after regeneration has started but before regeneration has reached such an extent that large voltage swings in the regeneration circuit are transmitted back to the signal source and corrupt the signal source or, by cross-talk, neighbouring circuits. Optionally, by means of a control circuit, the instant of isolating the signal source can be dependent on the degree of regeneration, for example, dependent on a predetermined degree of regeneration. The comparator may be incorporated in an electronic device such as an analogue-to-digital converter.
Abstract:
Some embodiments include apparatuses having input nodes to receive input signals, output nodes to provide output signals, a first stage including a first pair of input transistors, the first pair of transistors including gates coupled to the input nodes, a second stage including a second pair of input transistors, the second pair of transistors including gates coupled to the input nodes, and a third stage including inverters coupled to the output nodes. The inverters are coupled to the first and second stages at the same nodes to switch the output signals between different voltages based on the input signals.
